Usage: $0 [options] <feature1> <feature2> <feature3>
  Options:
          -d --dsn        The database name ($DSN)
          -a --adaptor    The storage adaptor to use ($ADAPTOR)
          -n --name       Delete features based on name or wildcard pattern (default)
          -t --type       Delete features based on type
          -i --id         Delete features based on primary id
          -v --verbose    Turn on verbose progress reporting (default)
             --noverbose  Turn off verbose progress reporting
          --dryrun        Dry run; report features to be deleted without actually deleting them
          -u --user       User to connect to database as
          -p --password   Password to use to connect to database
          -f --fast       Deletes each item instantly not atomic for full dataset (mainly for deleting massive datasets linked to a type)

Examples:
  
 Delete from mysql database volvox features named f08 f09 f10
     $0 -d volvox -n f08 f09 f10

 Delete features whose names start with f  
     $0 -d volvox -n 'f*'

 Delete all features of type remark, source example
     $0 -d volvox -t remark:example

 Delete all remark features, regardless of source
     $0 -d volvox -t 'remark:*'

 Delete the feature with ID 1234
     $0 -d volvox -i 1234

 Delete all features named f* from a berkeleydb database
     $0 -a berkeleydb -d /usr/local/share/db/volvox -n 'f*'

Remember to protect wildcards against shell interpretation by putting
single quotes around them!
